invention relates to a machine for cuttingxand slicing animal and vegetable products, such asmeat,"fat, cabbage, potatoes, etc.

. so that slices will result adaptable and confivenient for subsequent rendering, frying or other operations. 7

' Theinvention further relates to a machine which acts upon material to be sliced thru the medium of centrifugal 'force, functioning in such a manner that the centrifugal force coor- --"dinat'i1 1g with the inertia of a moving mass of material throws such material against a plurality of knives.

In the;prior art, various proposalsohave "beenemadeltorsliee and out materialsby machinery. "Many of these proposalshaveem- ,ployed. rotating discs together with cooperating knives, ;bntthey "haveebeen unsatisfac- -tory'because 70f 'thelapplicationiof gravita- I tional Iforce to provide .the cutting pressure,

, resultingiin irregular, hit and miss slicing,

or :jamming .of the machine. In order to .overcome this so-called gravitationalz slicing pressure, springs have been resorted to, to ap- 125 -ply pressure normal. to gravity, but this has only-aggravated matters as springs take up valuable machine space, become rusty and eventually lose their resiliency. 4 v

II have discovered athat satisfactory and -regular cuttingmay be obtained by the methodrand apparatus A I Y employ; thus obviating v.-the"disadvantagesof the prior art. a

.My: preferred apparatus is s shown. in the drawings.

Figure 5 is a horizontal section taken on line 5-5 of Figure 4 showing the knife blade attached to the cylinder wall. 7

Figure 6 is a view along line 6-6 of ure 5 showing one of the knives in positiom.

Referring to the drawings, and specifically to Figure 4, the flanged posts 1 are suitably 53150 supported upon the upright standards 2. Se-

-bystuds toibearing support. 25 preventsupward displacement of the gear 26. YThetop showing the means of attaching the gears to cured to these posts is theouter cylindrical member 3. A top spider 5 is supported by and secured to the top flanges 4: of'the posts,

and an inner cylinder 6 depends from said spider and forms with the outer cylinder- 3 anannular channel'7. The innercy'lin'der' 6 is provided with a plurality of-verticalslote 1 like substantially tangential apertures Y e, in eaclr of which a -knifeublade 9, specifically shown in Figures -5 and'6 is mounted.

Resting upon the shelf 10 carried by standards 2 are thebearingsupports and bearings "l0"and 1l in which shafts 12 and 13=are'respectively-adapted to rotate; shaft 12 being actuated by the power transmitted bybelt' 15 v and pulley 14:, while shaft 13 is rotated by en aging gears 16-and'17.

The shaft 12 carries the fixed ccllarI8 to which 7 is secured the plate "19 and I disc 20 adapted to rotate therewith. The disc -20has attached thereto a plurality of scoops "'21 also adaptedtorotate in the interior 22 of cylinder 6.

Suitably supported by the upper portion of standards2 is a plate 23xwhi'ch' carries onits 'under-side'the shaft bearing 24 and; on its upper side the ball-bearing support-25. ,E'The gear 26 has formed therein the" to race for the ball-bearing and rotates' thereon, being actuated by theengaging gear 27 fixed to shaft 8 1-3. The gear 26 has securedthereto the Z shapedelement 28, which in turn -carries thedisc 29, adapted tobe the rotating bottom of. the annulus 7. "The member 30 attached plate81 is providedwith a circular fc-utout portion while top plate 32 providesa top closureforchannel 7.

Referring to'Figure 2 it will be seenthat the annular passage? contains baffleplatef33 secured to .thecylinder 3. "Adjacent to this f -baffie zplate,the cylinder 3' has a cut-outjdischarge opening'S i which communicates with "a 'dischargeapron 35.

The slicesare ejected thru the vertical slot apertures onto the r tating disc 29, which carries the slices around till they meet the baffle plate 33, which d1- verts them thru the, discharge opening 34. The discs and 29 are adapted to revolve 1n 1 q the same direction asshown by the arrows.

The mechanism I have described is com-.

pact, easily. assembled, and the parts are, conveniently replaceable, without any sacrifice of ruggedness nor endurance necessary for continuous operat on- Thekmfe blades are replaceable and adjustable by virtue of the slots 41 shownin Figure 6. While I have. shown the various parts secured together by bolts and nuts, if desired the various parts .may be secured in any other well-knownmanner, as by welding, if expedient. It is also within my invention to change the angular .di- 7 rection of the scoops 21 and to make other minor changes in mechanical features. 7
